Title: Method for detecting substance in supporting body
Inventor: OOSAWA KAZUSAWA
IPC: G01N31/22
Filed: 1983-07-11
Abstract: PURPOSE:To detect a substance to be detected rapidly with high sensitivity by dipping a tested substance expansion supporting body into a hypertonic liquid to contract the supporting body and then dipping the supporting body into a hypotonic liquid to expand the supporting body so that a coloring matter of metallic salt is contacted with the supporting body in any process out of said two processes. CONSTITUTION:When the tested substance expansion supporting body is dipped into the hypertonic liquid for 5-30min, the supporting body is contracted. A water soluble organic compound such as polyethylene glycol is preferable for the hypertonic liquid. Subsequently, the contracted supporting body is dipped into the hypotonic liquid to expand the supporting body. Water, a buffer solution or the like is usually used as the hypotonic liquid. The dipping period into the hypotonic liquid is preferably 2-20min. In the contracting or expanding process, the supporting substance is contacted with a detecting reagent. A coloring matter such as methylene blue and safranine-o or metallic salt such as silver-amino complex salt and silver nitrate can be used as the detecting reagent.

Title: Apparatus for measuring concentration of rare gas
Inventor: TAURA MASAZUMI
IPC: G01N21/67
Filed: 1986-05-30
Abstract: PURPOSE:To measure the concn. of rare gas, from which a background due to the beam emission of nitrogen is removed, accurately and continuously, by simultaneously detecting the beam emission of nitrogen gas and that of rare gas and performing signal processing on the basis of both detection signals. CONSTITUTION:Sample gas comprising rare gas containing nitrogen gas is supplied to a discharge pipe 21 from a supply pipe 23 and the sample gas of the discharge pipe 21 is discharged from a discharge line 25 by a vacuum pump 26. At this time, when high voltage is applied to the discharge pipe 21 from a high voltage power source 22, the sample gas discharges to emit beam. This beam is split into two luminous fluxes by a beam splitter 28 and one of the luminous fluxes is allowed to pass through an optical filter 29 of which the center wavelength is matched with the molecular beam emission of nitrogen to be detected by a detector 30. The other luminous flux passes through a spectroscope 31 of which the center wavelength is matched with the peak of the atomic beam emission of the rare gas to be detected by a detector 32. The output signals of both detectors pass through an amplifier 33 and both amplified signals are compared by a computer 34 and operationally processed. By this method, the concn. of the rare gas can be measured accurately and continuously on the basis of the beam emission intensity of the rare gas from which a background due to the beam emission of the nitrogen molecule is removed.

Title: Automatic make and break system of power supply
Inventor: KOUNO EIICHI
IPC: G06F1/32
Filed: 1984-06-19
Abstract: PURPOSE:To prevent the increase of a critical hardware fault as well as the useless break of a power supply in an automatic make/break system of power supply, by cutting off a system power supply unconditionally when said fault occurs and then suppressing the application of the power supply. CONSTITUTION:A timer 32 transmits signals to a power supply application circuit 33 at a reserved time point for application of power supply. A power supply control circuit 16 applies a system power supply to start the operation of a system 10. If a critical hardware fault occurs, a power supply cut-off indication is sent to a power supply cut-off device 20 from an instruction controller 13. At the same time, the timer 32 is set to suppress the subsequent application of power supply. When the power supply is cut off after the processing is over, the present time point is compared with a reserved time point for the next application of power supply. Then the power supply is not cut off and the next processing is carried out if the present time is larger than the reserved time. This prevents the useless cut-off of the power supply.
